Harmonic Highlights:

  • Prevalent ii-V-I progressions (Dm7-G7-C6) firmly establish the C major key center.
  • G13sus chords resolve to G7, building tension before V7-I resolution.
  • Secondary dominant A7 (V7/ii) temporarily tonicizes Dm7, adding harmonic movement.
  • Strategic use of bVII7 (F7) as a backdoor dominant and a ii-V of IV (Gm7-C7) preparing modulation.

Improvisation Focus: Emphasize outlining ii-V-I progressions with arpeggios, Mixolydian, and Dorian scales.

Difficulty Rating: 3 (Intermediate). The harmony features common jazz progressions and extensions, requiring awareness of diatonic and secondary dominant relationships.
